French & Double Doors

French & Double Doors in Hobe Sound, FL | Sightline Windows & Doors Hobe Sound

French & Double Doors bring wide, symmetrical openings to Hobe Sound homes, folding interior living space into patios, poolsides, and ocean-view terraces. In coastal Florida, those openings have to survive what the Atlantic season throws at them. That’s where impact-rated French doors change the equation. At Sightline Windows & Doors Hobe Sound, we sell and install paired impact French and double door systems across PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass product lines. Every unit we quote carries laminated glass, multi-point locking hardware, and Miami-Dade NOA or Florida Product Approval documentation for its exact configuration. We’ve fitted these doors in homes from Jupiter Island to Jonathan’s Landing, and we know how Hobe Sound’s salt air, coastal wind exposure, and HVHZ permitting environment shape what actually works on your wall.

Product Overview - French & Double Doors

Our French & Double Doors are paired impact-rated systems with laminated glass in every lite, built for interior-to-exterior openings where homeowners want maximum light and a clean, symmetrical sightline. The defining character is the even division: left and right panels mirror each other, creating that classic French door proportion whether you’re stepping out to a pool deck in Hobe Sound or framing a view across the Indian River Lagoon.

These doors suit a wide architectural range. We’ve installed them in Mediterranean estates near Gomez Avenue, coastal ranch homes off Bridge Road, and contemporary builds in Hobe Sound’s newer developments. The aluminum and vinyl frame options let us match structural requirements with aesthetic preference. Aluminum delivers slim sightlines and strength for oversized openings; vinyl offers thermal separation and a softer visual weight that works well with painted coastal palettes.

Multi-point locking hardware secures the active panel at several points along the frame, not just at the handle. That matters in hurricane conditions because it distributes wind load and reduces the chance of panel flex or seal failure. The passive panel locks top and bottom, creating a unified wall of glass that behaves as a single structural element when pressure builds. Every lite contains laminated impact glass, so if debris strikes, the PVB interlayer holds the fragments in place and maintains the envelope.

Hurricane & Compliance Performance

Laminated Impact Glass
The glass in every lite is laminated with a PVB (polyvinyl butyral) interlayer. If wind-borne debris strikes the surface, the glass may crack but the interlayer holds the shards captive in the frame. That preserves the pressure envelope and prevents the catastrophic breach that turns a storm into interior destruction.

Miami-Dade NOA / Florida Product Approval
Every configuration we quote carries its own Miami-Dade Notice of Acceptance and Florida Product Approval numbers. These are not blanket certifications. The NOA is issued per specific size, glass type, frame material, and hardware set. We verify the numbers on your quote match your permit submittal exactly.

FBC / HVHZ Compliance
These doors are engineered to Florida Building Code High-Velocity Hurricane Zone requirements. Hobe Sound sits within Martin County’s HVHZ jurisdiction, so your permit inspector will check for valid NOA documentation and proper installation labeling. We handle that documentation as standard practice.

TAS 201 / 202 / 203 Testing Context
HVHZ-rated products undergo the TAS protocol family: TAS 201 for large-missile impact resistance, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. These tests simulate what a door faces during a hurricane event - flying debris, pulsing pressure, and attempted breach after the glass is damaged.

Design Pressure for Your Wind Zone
Design pressure is a PSF rating, not a wind speed. We match the door’s rating to your specific wind zone, up to +/-100 PSF. A Hobe Sound home on the Intracoastal may need a different rating than one set back on higher ground. We calculate this from your address and structure height, never overselling capacity you don’t need.

Energy Performance
Low-E insulated glass options are available for every frame material. In Hobe Sound’s climate, Low-E coatings reduce solar heat gain through south- and west-facing doors without the visual darkness of heavy tinting. Insulated glass also reduces condensation on interior surfaces during humid mornings.

Color & Glass Options

Hobe Sound’s coastal and Mediterranean architecture gives our five standard finishes distinct roles. White remains the default for stucco exteriors, reflecting heat and blending with trim. Almond softens the contrast on cream or sand-colored walls common in older Hobe Sound neighborhoods. Bronze carries a traditional Florida feel that pairs well with terracotta roofs and darkened window walls. Black has become the choice for contemporary builds from Hobe Sound to Jupiter, creating sharp sightline definition against light stucco or natural stone. Tan bridges warm and neutral, working where the landscape palette leans toward native scrub and sand.

Glass selection follows function. Laminated impact glass is non-negotiable for HVHZ compliance and comes standard. Low-E insulated glass adds thermal performance for doors that catch afternoon sun across a patio or pool deck. Tinted glass suits west walls where solar control matters more than light quantity. Clear glass maximizes views where external shading - deep overhangs, pergolas, or landscape - handles solar gain instead. We’ll walk your site and recommend based on orientation, neighboring structures, and how you use the space.

Installation by Sightline Windows & Doors Hobe Sound in Hobe Sound

A Miami-Dade NOA-rated door is only as good as its installation. We’ve seen properly specified systems fail because the frame wasn’t shimmed square, the perimeter seal was skipped, or the wrong fastener pulled through the jamb. In Hobe Sound’s HVHZ environment, that isn’t a maintenance issue - it’s a code violation and a safety gap.

Our process starts with a pre-install inspection. We measure the rough opening, check for plumb and level, and identify any structural modifications needed. Hobe Sound’s coastal exposure means we often encounter salt-damaged framing around older door openings, especially on oceanfront and Intracoastal properties. We flag that before the product arrives, not during.

Setting follows AAMA 2400/2410 installation standards. The frame is leveled, plumbed, and squared in the opening, then fastened per manufacturer specification for your specific NOA. We use AAMA 812 low-expansion foam perimeter sealant to create a continuous air and water barrier between frame and rough opening. This matters in Hobe Sound because wind-driven rain hits hard and finds every gap.

After setting, we run a water test, operate the multi-point lock through full cycles, and verify sweep and weatherstrip contact. Cleanup removes installation debris; we don’t leave your patio looking like a job site. Permitting awareness is built in - we know Martin County inspectors check NOA labels, fastener schedules, and foam seal continuity. Our paperwork package supports your permit closeout without chase calls.

Improper installation voids the performance the NOA promises. That’s why we don’t subcontract to traveling crews or hand this off to generalists. Our installers work exclusively on impact window and door systems in Hobe Sound and surrounding Martin and northern Palm Beach counties.

Frequently Asked Questions - French & Double Doors

What wind zone / design pressure is the French & Double Doors rated for?
Design pressures are matched to your specific wind zone, up to +/-100 PSF. We calculate the required rating from your Hobe Sound address, structure height, and exposure category. Call (772) 362-5967 and we’ll confirm the exact PSF for your project - estimates are free.

What is the lead time?
Lead times vary by manufacturer line, frame material, and glass option. PGT and CGI typically run shorter than custom-configured ES Windows or ECO orders. We quote current production schedules at measurement and can often suggest alternate lines if your timeline is fixed. Call (772) 362-5967 for current availability.

Does it require a Miami-Dade NOA or Florida Product Approval submittal for my permit?
Yes. Hobe Sound falls under HVHZ jurisdiction, and Martin County building officials require valid NOA or Florida Product Approval documentation for every impact door installation. We provide the specific approval numbers for your configuration with your quote and include them in our permit support package. Call (772) 362-5967 to start the documentation process.

Can I customize the size or configuration?
Standard configurations run up to 96 inches wide. Within that range, we can vary height, panel ratio, swing direction, and hardware placement. Custom sizes beyond catalog standards may be available on select lines with extended lead times. We measure your opening and quote only configurations that carry valid NOA coverage. Call (772) 362-5967 to discuss your specific opening.

How do I maintain the frame and hardware?
Rinse aluminum and vinyl frames quarterly with fresh water to remove salt accumulation, especially on oceanfront and Intracoastal Hobe Sound properties. Lubricate multi-point lock mechanisms annually with a silicone-based product. Avoid petroleum greases that attract grit. Inspect weatherstrip for compression set every two years and replace if daylight shows through the closed door. Call (772) 362-5967 if you notice lock drag or seal gaps - we service what we install.
